Summary
On April 24, 2026, German prosecutors launched an investigation into a series of phishing attacks targeting lawmakers, diplomats, and journalists via the Signal messaging app. The attacks reportedly compromised the Signal account of Bundestag President Julia Kloeckner and attempted to breach Chancellor Friedrich Merz's account. The domestic intelligence service BfV has indicated that these attacks are likely state-sponsored, with a focus on social engineering tactics rather than malware. Security services have warned that many Signal group communications may be compromised, raising concerns about the integrity of sensitive discussions. The campaign has been ongoing since mid-April, with indications that it is gaining momentum. The investigation aims to uncover the extent of the attacks and identify the perpetrators, with strong suspicions pointing towards Russian involvement. The situation underscores the vulnerabilities of messaging apps used by government officials. Key Points: • Phishing attacks have targeted high-profile German politicians using the Signal app. • Bundestag President Julia Kloeckner's Signal account was compromised, and Chancellor Merz's account was targeted. • The attacks are believed to be state-sponsored, likely linked to Russia, using social engineering techniques.
